Chromegabond WR C18

Chromegabond WR (Wide Range) is specially deactivated to produce superior peak shapes for amines and acids. Chromegabond WR C18 superior performance is the result of a multistep process beginning with ultra-pure synthetically produced spherical silica. The ultra-pure silica particles are then fully hydroxylated before they undergo an extensive bonding monomeric C18 alkyl chains, using proprietary bonding procedures. The bonded particles are then exhaustively endcapped to react any remaining silanol groups yielding columns that are much more resistant to degradation by acidic and basic mobile phase compositions, while improving peak shapes for amines and acids.

FluoroSep-RP Phenyl

FluoroSep-RP Phenyl is a truly unique stationary phase with properties significantly different than ODS phases. This unique character results from bonded pentafluorophenyl groups imparting a pi-pi electron interaction which produces an enhanced retention for many compounds particularly those that contain polarizable electrons. Many classes of compounds contain polarizable electrons including halogenated compounds, aromatics, and conjugated systems. Many naturally occurring chemicals also contain polarizable electrons and can be separated using FluoroSep-RP Phenyl.
